Re bonjour,
Un autre truc qui chez moi fait bien les choses, je pense que c'est la solution :
Re: [ADAPTABLE] THEME SUPPORT ONLY
The title text length is a setting that you can change in the Header section. By default is 50% and you can change it to 70%-80% to display the complete title.
The logo in the title depends of Display site title and the logo. If you add the logo, the setting is disabled. If you do not add the logo then the title setting is enabled.
